20080198741 | Method for Providing Alternative Paths as a Rapdid Reaction to the Failure of a Link Between Two Routing Domains - The present disclosure relates to a method for providing substitute routes in rapid response to the failure of a link between two routing domains in a packet-oriented network. After the failure of a link has been identified, substitute routes are provided for routes which have been interrupted by said failure by locally selecting alternative routes and propagating messages along the substitute routes. In order to provide substitute routes, an inter-domain router checks whether the router contains a substitute route. If there is no substitute route, a request message is transmitted to at least one adjacent inter-domain router and the transmission of at least one substitute route is thus requested. If there is a substitute route in the adjacent inter-domain router, the inter-domain router making the enquiries is informed of this in a response message. The present disclosure thus results in the improved provision of substitute routes in response to disruptions in inter-domain routing. | 08-21-2008 |
20090016213 | METHOD FOR EFFICIENTLY TREATING DISTURBANCES IN THE PACKET-BASED TRANSMISSION OF TRAFFIC - The present disclosure relates to methods for efficiently treating disturbances in the packet-based transmission of traffic by means of a routing protocol and routing entities. According to an exemplary embodiment, a message signaling the non-availability of a neighboring routing entity is inspected. Once the message signaling the non-availability of a neighboring routing entity is received, a test message for verifying the information is sent. If the non-availability is confirmed upon inspection, the system deduces that there is a failure of the connection to the neighboring routing entity. The routing entity then occasions a change in routing in order to circumvent the failed connection. This configuration reduces the operations required for fault recovery in the network and protects the system from false error messages generated to disturb the network. | 01-15-2009 |
20100254256 | METHOD FOR EFFICIENTLY TREATING DISTURBANCES IN THE PACKET-BASED TRANSMISSION OF TRAFFIC - A method for efficiently treating disturbances in a packet-based transmission of traffic via a routing protocol and routing entities includes reporting the nonavailability of a neighboring routing entity to a routing entity with regard to the routing by means of the routing protocol, initiating the sending of a test message from the routing entity to the neighboring routing entity for determining availability, wherein, when the nonavailability is confirmed as part of the verification, a failure of the connection to the neighboring routing entity is assumed, and initiating a change in the routing for avoiding the failed connection by the routing entity when nonavailability of the neighboring routing entity is confirmed. | 10-07-2010 |
